## Installing the modules
-If you're using Ubuntu, Evan Broder has packaged the scripts.mit.edu modules for all current Ubuntu releases in a PPA.
+If you're using Ubuntu, Evan Broder has packaged the scripts.mit.edu modules for all current Ubuntu releases (through 11.x) in a PPA.
The [PPA homepage](https://launchpad.net/~broder/+archive/scripts-http-mods) includes instructions on how to install the PPA on your system, but if you're on Ubuntu Karmic or later, you can just run:
- # add-apt-repository ppa:broder/scripts-http-mods
+ # add-apt-repository ppa:broder/scripts-http-mods ; apt-get update
Once you've installed the PPA, you want to install the libapache2-mod-auth-sslcert and libapache2-mod-authz-afsgroup packages.

-You also need to require certificate authentication. You can either use `SSLVerifyClient required` or `SSLVerifyClient optional`. `SSLVerifyClient required` has the downside that, if visitors don't have client-side certificates, they'll get an obscure OpenSSL error. However, Safari will not present certificates to a site with `SSLVerifyClient optional` set unless the user sets up an Identity Preference. For reference, scripts.mit.edu sets `SSLVerifyClient optional`.

You'll also need to enable the Apache modules.
